CONSTITUTION: A PST(Product Support Tool) program and a download program of a PC is executed successively(S101). The PST program transmits a flag requesting for an ID of a flash memory of a terminal to the terminal through serial communication(S102). The terminal transmits the ID of the flash memory stored in a nonvolatile memory through a RS-232 cable to the PC for prompt response to the request(S103). A user selects a binary file corresponding to the flash memory adapted to the terminal in a sub directory of a user's PC on the basis of information of the flash memory(S104) and decides whether or not the selected binary file is selected correctly(S105). If the file is selected correctly, the user selects start button of the PST program so as to download the binary file, the PST program starts download and the terminal downloads the binary file through continuous communication with the PC(S106). If download is completed, the PST program displays a message reporting completion of download on a screen of the PC and stops the download(S108).

Description

Method for down loading file to mobile station from a personal computer}

The present invention relates to a file download method from a personal computer (hereinafter referred to as a PC) to a terminal, and in particular, a file download by adding a unique ID to a flash memory applied to each terminal model. The present invention relates to a method of downloading a file from a PC to a terminal so that the correct data (Binary File) can be reliably downloaded to the terminal after checking the ID of the flash memory using a time program. That is, the present invention relates to a download program of a PST (Product Support Tool) window program of a PC, and a binary file that is actually downloaded to a terminal according to the type of flash memory used for each terminal model at the time of downloading each flash. The idea is that it depends on the memory model.

Existing download programs have different binary files depending on the type of flash memory applied to the model of the terminal. Therefore, when actually downloading the file from the PC to the terminal, it was necessary to know the flash memory according to the type of terminal to download the correct file. In other words, it is necessary to first understand the flash memory of the terminal. Therefore, when two or more flash memories are applied to a terminal model, a worst case situation in which the user needs to disassemble the device of the terminal in order to know the type of flash memory may occur. That is, since the DOS download program corresponding to each flash memory type is different, there is another troublesome problem that needs to be checked.

In addition, if the type of flash memory applied to the terminal is checked and the corresponding download program matches, the download program is executed if the binary files to be downloaded are different and the size is the same. However, after downloading, because the binary files are different, the terminal does not work (power is not turned on), or if the flash memory has to be replaced.

Therefore, conventionally, physical, human, and time loss occurs when downloading a file.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to add a unique ID for each type of flash memory applied to each terminal model to identify the ID of the flash memory using a program when downloading a file. After that, the present invention provides a method for downloading a file from a PC to a terminal so that accurate data (Binary File) can be stably downloaded to the terminal.

A feature of the PC-to-terminal file download method according to the present invention for achieving the above object is, in the method of downloading a file from the PC to the terminal, the type of flash memory of each manufacturer in the one memory of the PC, the corresponding flash Storing the unique ID of the memory and the size of the flash memory, and storing the unique ID of the flash memory applied to the corresponding terminal in the nonvolatile memory of the terminal; Executing a download program using the PST program of the PC and turning on the terminal at the same time, the PC requesting a flash memory ID from the PC to download using serial communication; The terminal reads the flash memory ID information stored in the nonvolatile memory according to the ID request signal from the PC and transmits the flash memory ID information to the PC; The PC compares the ID information of the corresponding flash memory transmitted from the terminal with the ID of a plurality of flash memories stored in one memory of the PC, and the type, size, ID, and file of the flash memory of the corresponding terminal. Displaying a file selection text box on which a screen can be selected; And selecting a file corresponding to the type and size of the displayed flash memory and downloading the selected file to the terminal.

Hereinafter, a method of downloading a file from a PC to a terminal according to the present invention will be described in detail with reference to the accompanying drawings.

First, divide the flash memory manufacturer (Intel, Sharp, Mizbish, etc.) and size (8K, 16K, etc.) and define their unique IDs for various types of flash memory models applied to the terminal as shown in Table 1 below. I will use it.

ID Flash memory type size 0 × 0 0 Intel 8K 0 × 0 1 Intel 16K ...... ..... ... 0 × 1 0 Sharp 8K 0 × 1 1 Sharp 16K ...... ..... ... 0 × 2 0 Mizbish 8K 0 × 2 1 Mizbish 16K ...... ..... ... Etc Etc Etc

In addition, in order to respond to signals emitted from the PC through the PST program, a response flag (eg FLASH_ID_REQUEST_F, FLASH_ID_RESPONSE_F, etc.) is added to respond to the terminal software source file (eg, diagp.c). .

In addition, when the download program is powered on, the terminal and the PC immediately start communication due to serial communication, and simultaneously send out a request flag and a response flag to flash memory of the terminal. Get the ID.

In addition, since the flash memory ID can be used from 0x0 0 to 0x0 9, for example, Intel can be used for continuous up-date.

If there is no response flag for the request flag, it is treated as an error quickly, and an error message is output to cancel the download program, or an external cause for the user to easily solve the error, such as terminal power off or RS-232. Print a message to correct when the cable is not properly connected.

1 is a view showing a configuration in which the main body of the PC and the terminal is connected via an RS-232 cable, Figure 2 is a schematic block diagram of a terminal applied to the file download method from the PC to the terminal according to the present invention, First, as illustrated in FIG. 1, in order to download a file from a PC to a terminal, the main body of the PC 10 and the translator 20 are connected with an RS-232 cable, and the translator 20 and the terminal 30 are also connected. Must also be connected via RS-232 cable. In addition, in the configuration of a general terminal applied to the present invention shown in Figure 2, the main processor 33 for managing and controlling all the functions of the terminal, the RF unit 31 responsible for transmitting and receiving wireless data, and the terminal LCD (37) for displaying the status of the user, a nonvolatile memory (34) for storing user information and call information, a key input section (32) for providing a key input signal for operation of the terminal to the main processor (33); And a program memory 35 in which a terminal control program is stored and a data memory 36 in which data necessary for operating a terminal is stored.

Hereinafter, a method of downloading a file from a PC to a terminal according to the present invention will be described in detail with reference to FIGS. 3 and 4.

First, the PC 10 is set up by the initialization operation (S101). That is, the PST program of the PC 10 is executed, followed immediately by the download program. At this time, the user should turn on the power of the terminal 30 in 3 seconds to 5 seconds in accordance with the message output to the screen from the download program.

Subsequently, the PST program sends a flag requesting the ID of the flash memory of the terminal to the terminal 30 using serial communication. That is, the terminal responds to the PC 10 via the RS-232 cable with the flash memory ID stored in its nonvolatile memory 34 in order to immediately respond to the request. Here, among the IDs of the flash memories shown in Table 1 and the sizes of the flash memories, the IDs of the flash memories and the sizes of the corresponding flash memories applied to the corresponding terminal 30 for downloading are shown in FIG. 2. The state is stored in the nonvolatile memory 34 of the terminal, and the PC stores the manufacturer, ID, and size value of each flash memory shown in Table 1. .

Accordingly, the PC 10 compares the ID data of the response signal transmitted from the terminal 30 and the flash memory applied to the terminal with a flash memory ID table as shown in Table 1 coded in the PST program in the program. It identifies the type of flash memory and displays it on the screen as shown in FIG. 3A for the user to see at a glance.

Referring to FIG. 3A, a flash memory ID value applied to the corresponding terminal 30 read from the terminal 30 is output to a text box indicating the flash memory ID on the screen as it is, and the flash is displayed next to the screen. A text box indicating the type of memory will display the type and size of the flash memory.

In addition, the text box labeled Selected File shows the directory where the program is currently installed, and the Select File command button is a command button that allows you to select a binary directory from the actual directory.

Then, the Start button under the Select File button is a command button that allows the user to download the file to the terminal 30 using this button after selecting a binary file, and the Exit button under the Start button is used to terminate the download. Button. Then, there is a bar-shaped screen which shows the progress speed and the progress of the download.

Subsequently, the user selects a binary file corresponding to the flash memory applied to the terminal 30 from the sub directory of the PC 10 based on the information about the flash memory responded in step S103 (S104). This file contains the software to use the actual terminal.

In operation S105, it is determined whether the selected binary file is correctly selected.

As a result of determination, if a binary file is incorrectly selected, an error message is output on the screen, and the feedback is returned to step S104 to reselect the flash memory ID and the corresponding binary file.

On the other hand, when the binary file is correctly selected in step S105, in order to download the selected file to the terminal, the user selects the Start button of the PST program and starts the download of the PST program, and the terminal 30 continues with the PC 10. The binary file is downloaded through communication (S106). 3B shows the PST program at this time on the screen. The text box of the selected file indicates the location of the file to be downloaded to the actual terminal 30 and shows the progress of the actual download in the form of a bar.

Subsequently, if it is determined that the download is completed (S107), if the download is not completed, the download is continuously performed and the download progress is continuously displayed on the screen as shown in FIG. 3B, and if it is determined that the download is completed, that is, the download is completed. When 100% is completed, the PST program displays a message that the download is completed on the screen and stops downloading (S108). The user then confirms that the terminal has downloaded the download before pressing the Exit button, and then exits the download program. 3C illustrates an example of a screen displaying a message indicating that the download is completed after the download is completed.

Briefly summarizing the file download method from the PC to the terminal according to the present invention, the user turns on the terminal while simultaneously executing the download program using the PST program. At this time, the PC requests the ID of the flash memory from the terminal to determine the flash memory of the terminal using serial communication. The terminal receiving this request, in turn, responds to the PC with the ID information of the flash memory applied to its terminal stored in the nonvolatile memory of the receiver.

In response to this, the PST program compares the table of the program with the ID responded from the terminal to find out the type and size of the flash memory of the terminal. The ID is displayed on the screen of the PST program. Make it easy to find information about.

The user can find out the type and size of the flash memory of the terminal through the information provided, that is, search for and find the corresponding file in the subdirectory of the user's own PC, and select the file so that the terminal can select the binary file. To download it.

The method of downloading a file from a PC to a terminal according to the present invention as described above can solve a problem that occurs when downloading a binary file to a terminal of each model. That is, when two different flash memories are used in the same model, the type and size of the flash memory can be known only by opening the device of the terminal, and even if one flash memory is used in the same model, the above troublesome problem is required. By improving, it has the effect of minimizing the loss of human, material and time.

In addition, even if the flash memory and the download program of the terminal match, by downloading the wrong binary file, there is an advantage that can effectively reduce the physical and time loss, such as the terminal operation disabled or flash memory replacement.
